EPerformance Series
Ultimate EP Biplane
3D action on demand!

Push the sticks to the stops and the Ultimate Biplane will deliver spectacular aerobatic performance. Riveting rolling Harriers, tantalizingly slow torque rolls – with the Ultimate Biplane and your skills, the sky's no limit! Its compact size lets you push the limits, almost anytime and anywhere. Designed to deliver the best in brushless performance, it's also factory-built with the quality Great Planes is famed for. Light, straight wood structures. Painted fiberglass parts. And light, molded hardware for strong, split-second response.

  • Delivers big-time 3D performance even in small-space parks and ball fields.
  • Laser-cut wood airframe is prebuilt and covered, ready for simple, final assembly.
  • Includes hardware specially designed for E-Performance ARFs.
Laser-cut wood airframe
Great Planes makes it easy to enjoy the Ultimate Biplane's striking looks and outstanding performance in the shortest possible time. Its light, laser-cut wood airframe is factory-covered, and a full hardware package is included.


Includes a motor mount, hardware and a prop adapter
The Ultimate Biplane is designed for the spectacular power of a brushless outrunner motor. The ElectriFly RimFireTM 35-30-950 motor (GPMG4590) is a perfect choice, and includes a motor mount, hardware and a prop adapter.


The hook & loop strap holds your pack tight in-flight, but releases cleanly for quick, easy pack changes.


spacer Included hardware
The included hardware is purpose-designed for E-Performance perfection! Molded composite construction reduces weight and enhances precise, "right-now!" response.


Landing gear
Formed aluminum landing gear and lightweight wheels are just one facet of the Ultimate Bipe's light, weight-conscious design. Finishing accents include a fiberglass cowl and ABS wheel pants painted to match the trim scheme – the same one used on the 65" span Performance Series Ultimate Biplane!


spacer Dual servos
Impressive snaps and breathtaking roll rates are at your fingertips. Dual servos driving four ailerons deliver solid, authoritative control at any and all flight speeds.


Supersized control surfaces
Supersized control surfaces provide swift, powerful pitch and yaw control even at a crawl — a performance plus that experienced 3D pilots are sure to appreciate.


spacer Servos are mounted externally
Servos are mounted externally to speed and simplify installation and to guarantee the fastest, strongest response.


Maxed for 3D madness!
The Ultimate Biplane flies and feels bigger than other compact electrics. It's equally at home in a park or at a flying field, and throws can be fine-tuned for the way you want to fly: relaxed and easy, ready for pattern precision or maxed for 3D madness!


spacer View the Ultimate EP
Performance and appearance ensure that all eyes will be on the Ultimate Biplane, whether it's in the air or on the deck. Its one-piece design makes Ultimate Biplane lighter and stronger, and still an easy fit for almost any vehicle.


Don with Ultimate
"Like our glow-powered, IMAA-legal Ultimate Biplane ARF, this E-Performance version is designed for lightweight strength, pilot ease and aerobatic performance that can range from pleasantly mild to 3D wild! And since it's a compact electric, it can perform brilliantly in places where glow can't go!"
